There are multiple ways to send emails today, and while each offers a unique way to send these emails, there is only one way for emails to land directly in your customers inbox. Some of the most popular ways are:
- Use email marketing tools such as MailChimp to send mass campaigns. This is the simplest way to send emails, given the user friendliness and ease of use.
- Use of API based services such as SendGrid, MailGun, tad complex given it involves engineering, but the ease of documentation and all the Stack Overflow tutorials make life lot easier to send these email campaigns.
- Use of Gmail REST API to send and receive emails, by far, the most popular approach used today. Gmail also offers direct integration with PubSub, so for folks building mail apps, this is the best way to get notified when emails are sent and inboxes need to be synced.
Now, while all of these approaches seem fairly straight forward, they have one major drawback.
There is a high likelihood that emails sent by these services end up in Promotions tab or worst, the SPAM folder
To put things in perspective, given below is a screenshot of the biggest difference when an email is received via API / SMTP approach (sample email is from Kayak) vs being sent via compose window.
Emails sent via the compose window, contain the above 4 headers that are unique and one of the prime ways for emails to skip the promo tab completely and land directly in users inbox. From technical perspective, DKIM settings are used to prevent email spoofing (more at DKIM settings by Gmail), however, when the headers precede with “X-Google”, these are unique just to Google and the prime reason for emails to land directly in users inbox.
